[R] predict incosistency ?

[Jorge Luis Ojeda Cabrera]

When fitting model 'y~1', the 'lm' response is ok, but it is not possible 
to get predictions using 'predict'. May be this is a bug, at least i 
think it is somehow
inconsistent.

> rm(list=ls())
> d <- data.frame(x=runif(50),y=rnorm(50))
> plot(d)
> d.lm <- lm(y~1,data=d)
> d.lm

Call:
lm(formula = y ~ 1, data = d)

Coefficients:
(Intercept)  
     0.1654  

> mean(d$y)
[1] 0.1654461
> predict(d.lm,data.frame(x=0.5))
Error in x[[j]] : subscript out of bounds
> predict(d.lm,data.frame(x=c(0.05,0.25,0.5)))
Error in x[[j]] : subscript out of bounds

I am using a little bit older version
